We’re all familiar with thermally activated fuses, where the conducting element self-heats due to current flow, melts at a defined current value, and breaks the flow path. They are simple in concept ...

including understanding how the thermal and electrical characteristics of the fuse element behave. [Kerry]’s test setup is simple, consisting of a constant current power supply and a voltmeter ...

These fuses are designed to clear faults by expelling the fuse element once it melts, ensuring the circuit is disconnected while preventing damage. In various applications, expulsion fuses are ...

Smyrna, Ga.—Murata Electronics North America has introduced an anti-fuse element for light emitting diodes (LEDs). Developed to control open defects in LEDs, Murata's anti-fuse device prevents the ...

The fuse unit or fuse tube and renewable element should be examined for corrosion of the fuse element where the conductors are connected. • Excessive erosion of the inside of the fuse tube should be ...

The fix is to re-route current flow around the open LED. The anti-fuse element is connected in parallel to a serial LED, allowing each LED to stay lit should one become open. The result is ...
